Description
Detection was initially achieved utilising filters to separate the normal background noises from the sound of a tube leak. With the advent of modern digital sound analysis techniques - namely Fast Fourier Transforms (FFT) - frequency spectrums are generated for each audio sensor.

The analysis of these spectrums for a combination of frequencies determines the value of the alarm in percentage when a sensor channel is above a pre-set alarm value for a pre-set time when the leak alarm relay is activated.
